Science has shown that laughter is good for us, and perhaps no one knows that better than the founder of laughter yoga. Madan Kataria created this unique practice during a stressful time in his life, and though he’s an actual medical doctor, he created something entirely different to relieve stress. Bringing more oxygen into our bodies, lowering stress levels, and creating a new, happy mindset is his goal—and the 16,000 laughter clubs around the world have shown just what a contagious impact this unique form of yoga has had.
